IPv6 Checker & IPv4 Dual-Stack Test

IPv6 may be unavailable because your provider has not assigned IPv6 service, your router has IPv6 or prefix delegation disabled, or IPv6 is disabled on the active network adapter. Follow the three troubleshooting steps above, then run the check again.

An IPv6 route can be reachable but slower or less stable than the IPv4 route. Browsers may try IPv6 before or alongside IPv4, then fall back when needed. One slower result does not prove a permanent problem, but repeated slow or timed-out IPv6 checks are useful evidence when troubleshooting your provider, router, or device.

No. Different IPv4 and IPv6 exit paths can result from split tunneling, company policies, or different provider routes. This tool reports the difference without calling it a leak. Use a dedicated DNS or WebRTC leak test if you need a deeper privacy check.

Not as a default fix. A slow or unreliable IPv6 path can delay connections, but permanently disabling IPv6 can create other compatibility problems. First check the provider, router, and device settings, then compare repeated results from this tool.

The test reports whether this browser reached the IPv4 and IPv6 public endpoints at the time of the check. It does not test every destination on the internet or guarantee future route performance. Location and network details are approximate and depend on IP intelligence data.

The page shows your current public IP only for the active check. Recent checks, when enabled, are stored locally on your device. We do not use the history panel as a cloud account history.
